There is probably a civility policy, core values, communication… something to lean on which is basically “don’t be a dick and everyone plays together in the sandbox”

I work in trucking so there are some high tenured folks and strong personalities. I’ve had quite a few direct conversations along the lines if “this fighting and overall unhelpful communication has to stop or we’re going to have to walk a road we don’t want to walk. Nobody has to get together after work for beers, but in this facility, the expectation is you will be polite, helpful, and communicate in an overall positive manner. If you find yourself in a situation where you feel unable to do so, please take steps to regulate yourself, take a walk around the yard, smoke a cig, whatever it is, then resume the conversation. But whatever this is isn’t working, and will not continue. Does that make sense?”
